But the curve of accomplishments is not the same, nor is the incentive.
While China's manned program took a long time to go to a certain point, the trend is to keep going. NASA had quite a lull after Skylab before embarking on a multi-module space station. From the point of man in orbit, the programs also took different routes (moon vs space station).
So with the different goals from Gemini on, along with the change in technology since the early NASA programs, I find it hard to say anything about "behind" or even make any kind of progression comparison.
Out of curiosity, I tried to find some accomplishment milestone timelines for comparison. From this, you can see how different the advancement curves are.
NASA China
1954 1967 Manned space inception (x15, project 714)
1959 1986 Manned rocket program (Mercury, Project 863/921)
1961 2001 Animal test (MR2, Shenzhou 1)
1962 2003 Man in orbit (MA6, Shenzhou 5)
1965 2008 First EVA (Gem 4, Shenzhou 7)
1965 2012 First manned docking (Gem 8, Shenzhou 9)
1969 2025+ Man on the moon (A11, unknown)
1973 2016 Manned space station (Skylab, T2)(1)
1982 2011 Manned orbital research (STS, T1)(2)
2000 2020+ Multi-module space station habitation (ISS, T3)
(1) I used T2 because it's more on par with Skylab than T1. T1 is more on par (by size/capabilities) with MOL (without docking and never happened)
(2) This is where things get difficult because things diverge quite a bit here. But this entry is just to throw in some kind of orbital research capabilities.
It would probably be easier to compare China to Russia.
